Gravity Forms Redis Caching & High-Traffic Queue
Gravity Forms Redis Caching & High-Traffic Queue
Buffer spikes of submissions in Redis to eliminate database deadlocks during viral product launches.
1. Overview & Prerequisites
Gravity Forms Redis Caching & High-Traffic Queue is a high-performance, enterprise-grade integration addon engineered natively for Gravity Forms. It provides seamless bi-directional data flow, automated background event dispatching, and secure API credential management without relying on third-party webhook middleware or external SaaS pollers.
Before installing and activating this plugin, ensure your hosting environment satisfies the following baseline system prerequisites:
• WordPress Core: Version 6.0 or higher (fully tested up to WordPress 6.7+).
• Gravity Forms: Version 2.7 or higher (tested with Gravity Forms 2.8 and 2.9).
• PHP Runtime: PHP 8.0, 8.1, 8.2, or 8.3 with the cURL, OpenSSL, and JSON extensions enabled.
• HTTPS / SSL: A valid TLS 1.2+ SSL certificate is mandatory for secure API transmission and webhook callbacks.
• Outbound Firewall: Ensure your hosting server allows outbound HTTPS requests on port 443 to the target destination endpoints.
2. Installation & License Activation
You can install Gravity Forms Redis Caching & High-Traffic Queue using either the standard WordPress administrative dashboard or programmatically via WP-CLI / Composer.
Method A: WordPress Admin Upload
1. Download the signed distribution ZIP file from your GravityHive account dashboard or checkout confirmation email.
2. In your WordPress administration panel, navigate to Plugins → Add New → Upload Plugin.
3. Choose the downloaded ZIP file, click Install Now, and then click Activate Plugin.
Method B: License Key Activation
To ensure uninterrupted automatic security updates, patch delivery, and technical support, activate your license key:
1. In your WordPress dashboard, navigate to Forms → Settings → GravityHive Licenses.
2. Paste your 32-character license key into the designated field for Gravity Forms Redis Caching & High-Traffic Queue.
3. Click Activate License. Once verified, the status indicator will turn green, enabling one-click background updates from the standard WordPress Plugins page.
# Alternative WP-CLI installation command
wp plugin install /path/to/gravity-forms-redis-caching-queue-plugin-plugin-v1.0.0.zip --activate
wp option set gravityhive_gravity_forms_redis_caching_queue_plugin_license_key "YOUR_LICENSE_KEY_HERE"3. Feed Setup & Field Mapping
Once activated, Gravity Forms Redis Caching & High-Traffic Queue operates through Gravity Forms' native Feed Engine. A single form can support multiple distinct feeds with independent field mappings and conditional logic triggers.
Configuring Your First Feed:
1. Navigate to Forms → select the target form you wish to connect → click Form Settings.
2. In the left-hand navigation sidebar, click on Gravity Forms Redis Caching & High-Traffic Queue.
3. Click Add New to instantiate a new integration feed. Enter a descriptive feed name (e.g. "Primary Enterprise Sync").
4. Authenticate your API connection by providing your credentials or selecting an existing authenticated connection profile.
5. Map standard Gravity Forms fields (such as Name, Email, Phone, Company) to their corresponding destination schema attributes.
6. Optional Conditional Logic: Toggle 'Enable Condition' to specify routing rules (e.g., only dispatch data when 'Country' equals 'United States' or when 'Order Total' exceeds $100).
7. Click Save Settings. The feed is now live and will execute on every matching frontend submission.
4. Developer Hooks & Customization
For engineering teams with advanced customization requirements, Gravity Forms Redis Caching & High-Traffic Queue exposes clean WordPress filter and action hooks. These hooks allow you to mutate payloads, dynamically inject authentication headers, or handle custom callback events without modifying plugin source code.
Pre-Dispatch Payload Filter: Use the gform_gravity_forms_redis_caching_queue_plugin_before_dispatch filter to modify or enrich data before transmission.
Post-Dispatch Action Hook: Use the gform_gravity_forms_redis_caching_queue_plugin_after_dispatch action to trigger secondary internal workflows or log transaction responses upon successful completion.
/**
* Example: Custom hook to enrich payload before dispatching
* Place inside your theme's functions.php or a custom mu-plugin.
*/
add_filter( 'gform_gravity_forms_redis_caching_queue_plugin_before_dispatch', function( $payload, $form_id, $entry ) {
// Inject custom runtime environment metadata
$payload['dispatched_at'] = gmdate( 'Y-m-d\TH:i:s\Z' );
$payload['wp_environment'] = wp_get_environment_type();
$payload['user_ip_hash'] = hash( 'sha256', rgar( $entry, 'ip' ) );
// Conditionally override or sanitize sensitive parameters
if ( isset( $payload['notes'] ) ) {
$payload['notes'] = sanitize_textarea_field( $payload['notes'] );
}
return $payload;
}, 10, 3 );
/**
* Example: Capture downstream response ID and commit to entry meta
*/
add_action( 'gform_gravity_forms_redis_caching_queue_plugin_after_dispatch', function( $response, $entry_id, $form_id ) {
if ( is_array( $response ) && isset( $response['id'] ) ) {
gform_update_meta( $entry_id, 'gravityhive_gravity_forms_redis_caching_queue_plugin_remote_id', sanitize_text_field( $response['id'] ) );
}
}, 10, 3 );5. Troubleshooting & Diagnostics
When troubleshooting unexpected feed failures, authentication issues, or network timeouts, Gravity Forms provides native diagnostic logging.
Enabling Debug Logging:
1. Go to Forms → Settings → Logging.
2. Toggle Logging to 'Active' and locate Gravity Forms Redis Caching & High-Traffic Queue in the plugin list.
3. Set the log level to 'All Messages' or 'Log Warnings & Errors'. Click Save Settings.
4. Submit a test form entry on the frontend.
5. Return to the Logging settings page and click 'View Log' to inspect the detailed HTTP request and response payloads.
Common Diagnostic Status Codes:
• 401 / 403 Forbidden: Invalid or expired API credentials. Re-verify your access token in Form Settings.
• 422 Unprocessable Entity: A required field in the destination schema was left unmapped or failed validation format constraints.
• 429 Too Many Requests: Rate limit exceeded. The plugin automatically queues entries for exponential backoff retry.
• 500 / 504 Gateway Timeout: Downstream service outage. Check the third-party status page and retry failed entries from the Entry Detail screen.
6. Security & Data Governance
GravityHive adheres strictly to the highest enterprise data security and privacy engineering standards:
• Local Credential Encryption: Sensitive API keys, OAuth refresh tokens, and secret webhooks are encrypted at rest using WordPress cryptographic salts before being stored in the wp_options table.
• Zero Data Telemetry: Unlike generic middleware SaaS connectors, form submission payloads travel directly from your WordPress server to the destination API. GravityHive never proxies, inspects, or stores your customer submission data.
• GDPR & CCPA Compliance: All entry metadata generated by Gravity Forms Redis Caching & High-Traffic Queue is natively indexed against GravityForms core entries. When an administrator processes a WordPress 'Erase Personal Data' request, associated integration logs and tokens are wiped automatically.
• Action Scheduler Architecture: Background queues leverage the Action Scheduler engine, ensuring transactions execute reliably even on hosting providers with strict 30-second PHP maximum execution timeouts.
